In 2019,Organic Letters included an article by Lou, Jiang; Wang, Quannan; Zhou, Yong-Gui; Yu, Zhengkun. Category: iodides-buliding-blocks. The article was titled 《Rhodium(III)-Catalyzed Annulative Coupling of Sulfoxonium Ylides and Allenoates: An Arene C-H Activation/Cyclopropanation Cascade》. The information in the text is summarized as follows:
Rhodium(III)-catalyzed annulative coupling of sulfoxonium ylides with allenoates was achieved, forming highly functionalized cyclopropanes I (R1 = H, 3-F, 5-Me, etc.; R2 = Me, nBu, Bn, etc.; R3 = Et, iPr, Ph, etc.) with a quaternary carbon center by means of the sulfoxonium ylide functionality as a traceless bifunctional directing group and C4 synthon via an arene C-H activation and cyclopropanation cascade. The protocol features simultaneous formation of three new C-C bonds in one pot with excellent diastereoselectivity. The resultant cyclopropanation products could be further transformed to diverse synthetically useful compounds In addition to this study using Trimethylsulfoxonium iodide, there are many other studies that have used Trimethylsulfoxonium iodide(cas: 1774-47-6Category: iodides-buliding-blocks) was used in this study.
Trimethylsulfoxonium iodide(cas: 1774-47-6) reacts with sodium hydride to prepare dimethyloxosulfonium methylide, which is used as a methylene-transfer reagent in synthetic chemistry. It is used to prepare ylide, which reacts with carbonyl compounds to get epoxides. Further, it reacts with alfa,beta-unsaturated esters to get cyclopropyl esters.Category: iodides-buliding-blocks
